Gifted Issues Discussion homepage Forums Twice Exceptional WISC results - 33point difference PRI and VCI

I think a higher PRI may be more likely with dyslexic children. I am not sure where I got this information, maybe in the "dyslexia advantage" book?
Anyway, when the discrepancy between PRI/VCI is statistically significant then the higher PRI could indicate a language difficulty/disorder (check essentials of wisc-iv). However, your child's VCI is still decent so I doubt schools would believe there is anything there.
I would not worry about processing speed at all. It is generally lower than the other 3 scales. (wisc-iv essentials- assessment)
